70s. There was talent, and the big fights got made. The latter element failed, in both previous and subsequent eras!
70's are probably tops. I also think the 90's were pretty damn good with Lewis, Holyfield, Bowe, Tyson, Foreman, Moorer, Mercer, McCall, Morrison, Ruddock etc.
From 1963 to 1979 Liston, Ali, Frazier, Foreman, Holmes, all at the absolute primes of their careers and the willingness to fight each other. Factor in the very goods ( Fighters that probably win championships in other era's especially today's) like Bonevea, Patterson ( who was a champ) Terrell,Mathis, Williams,Quarry, Norton,Ellis,Lyle,Shavers, Young, and other decent fighters that on any given night could have a great performance and surprise a ATG. That time span was the best in Heavyweight boxing history in my opinion.
An era that sees a prime Ali, Frazier, Foreman and Holmes is very hard to beat. Then add in the top contenders like Norton, Young, Quarry, Ellis, Mathis, Lyle, Mac, Shavers ect. 1965-198(or there abouts) is the clear winner imo.
70s seems like the best. Even the contenders were the tops. I think they got a big push of the bigger heavyweights in the late 1960s and early 1970s with Ali ,, but mainly after Liston came in and stopped Patterson, which then changed the whole division. I think Liston beating Patterson was the turning point with heavyweights. The Marcianos and Pattersons and Johanssons were the thing of the past. The real division with bigger guys went forward.
Most people agree upon the 70s. I'm sure it was a fine era, but I wasn't born until 1980, so i can only speculate and try to catch old youtube videos. In my lifetime the 1990s were the best HW era! Three legendary top bosses like Tyson (even though he was already washed up, his mystique still followed him) Holyfield and Lewis, plus a whole slew of great contenders and even great journeyman fighters. I do believe fighters of the 1970s can claim to be slightly better athletes, since they fought more often usually, and fought 15 round fights.... But as a fan I actually prefer 10 and 12 round fights over the 15 rounders. I notice the 15 round fights usually have a much longer feeling out phase, and usually don't start picking up in pace until after the 4th or 5th round anyways. They also seem to go the distance more often, which is fine of course, but I feel guys in the 90s were legitimately going for the KO more often than not, which made for more exciting fights
I know from scoring fights with a few guys that 10 rounders are so much fun to score. Even in the 15 round era there are tons of 10 rounders. Fatigue conditioning and stamina become less of an issue, and the action and punch volume increase drastically! Count me in as another that loves 10 rounders
I agree - 1970s. 1970-1975 was the pinnacle. You had an all time great in Ali and then a bunch of guys who could test him and a couple who beat him.
